Don't miss the perfectly preserved mummies at this superb museum, located 4 km (2½ miles) northwest of the city center. The mummies—including the 4,000-year-old Beauty of Loulan—were excavated from tombs in various parts of Xinjiang. In addition, the museum has a well-executed exhibition on the region's ethnic minorities. If you are lucky, one of the museum's English-speaking guides will accompany you. There's no extra charge, and it's well worth asking.
